WINDOW HOLDER AND OPERATOR Filed June 1, 1965 2 SheetsSheet 2 x 55' 4 5646 Gw ye (Fl/gm United States Patent 3,357,735 WINDOW HOLDER ANDOPERATOR George C. Hayman, Denver, Colo., assignor to Leslie Welding(30., Inc., Franklin Park, Ill.,"a corporation of Delaware Filed June 1,1965, Ser. No. 460,113 7 Claims. (Cl. 292-270) The present inventionrelates to a novel window structure, and more specifically to a novelpushbar device for a window structure having an adjustable sash.

As will be understood, various window structures have heretofore beensuggested which utilize a sash mounted in a frame for pivotal movementbetween open and closed positions. It has further been suggested toprovide pushbar devices operable through fittings mounted on the windowframe for shifting the sash between the open and closed positions. Whilemany of such push-bar devices have been generally satisfactory, certainof such devices have been relatively difficult to mount or assemble, andcertain of such devices have been constructed so as to necessitate anopening through the window frame which would permit the passage ofinsects or other foreign material.

An important object of the present invention is to provide'a novelwindow structure including a pivotally mounted sash and an extendablepushbar device con structed so that the pushbar device may be axiallycollapsed or extended and adjusted for moving the sash between open andclosed positions without requiring an opening through frame means of thewindow structure which would permit the entry of insects or otherforeign material.

A more specific object of the present invention is to provide a novelpushbar device adapted to be shiftably mounted in an opening throughsuitable fitting or guide means and adapted to be axially extended orcollapsed and constructed in a manner so as to substantiallycompletelyfill and seal the opening through the fitting or guide means in variousadjusted positions.

A further important object of the present invention is to provide anovel pushbar device which is constructed so as to facilitate attachmentthereof to a window sash orvthe like. 7

Another object of the present invention is to provide a novel pushbardevice of the above described type which is of simple and economicalconstruction and which may be easily operated or adjusted.

Other objects and advantages of the present invention will becomeapparent from thefollowing description and the accompanying drawingswherein: 1

Referring now more specifically to the drawings wherein like parts aredesignated by thesame numerals throughout the various figures, a windowstructure 10 I in FIGS. 1 and 2 and the closed position shown in FIG.

3. Hinge means 16 and 18 are supporting the sash within the frame.

As indicated, the frame 12 may be of any suitable construction. However,the frame preferably includes vertically extending stop members 19 andlower and upper horizontally extending stop members 20 and 21. A 1

pushbar device 22 extends through the lower stop member 20 and isconnected with the sash for manipulating the sash between the open andclosed positions in the manner described in detail below.

As shown in FIGS. 2 and 6 the stop member 20 has an opening 23 thereinthrough which the pushbar device extends and is freely slidable. Afitting or guide member 24 is secured by screws 25 to the lower stopframe member 20. The fitting is provided with a guide opening oraperture 26 in alignment with the opening 23 for slidably receiving theshown.

The pushbar is adapted to be adjusted axially to an extended position asshown in FIGS. 1 and 2 for openpushbar device 22 in the manner ing thesash and to a retracted position as shown in broken lines in FIG. 3 forclosing the sash. Furthermore, the pushbar is adapted to be manipulatedfrom the broken line position in FIG. 3 to the full line position shownin FIG. 3 for interengagement with the latch member 32 fixed to theframe member 20. The latch' member 32 may be of known construction andserves releas'ably to retain the pushbar device in the full lineposition shown in FIG. 3 and thereby lock the window sash in the closedposition.

As shown best in FIGS. 4 through 9, the pushbar device 22 comprises afirst elongated bodyor channel member 34 having a top section 35 anddepending side sections 36 and 38 terminating in inturned flanges 40 and42 and combining to define a generally T-shaped slot 43. A handle member44 extends into the inner end of the slot 43 and is secured to thechannel member 34 by a suitable'fastener 45. The handle member ordeviceincludes a block 47 which completely traverses and seals the inner endof the T-shaped slot 43.

A second elongated body or slide member 46 is provided, which bodymember axially slidably extends within the T-shaped slot 43. The body orslide member 46 has a transverse cross-sectional configurationsubstantially identical to that of slot 43 and presents oppositelyextending flanges 49 and 51 cooperatively engageable with the inturnedflanges 40 and 42 of the channel member.

As shown best in FIG. 8, the slide member 46 substantially completelyfills the T-shaped slot and the bottom or exposed surface of the slidemember is coplanar with the bottom or exposed surfaces of the channelmember flanges 40 and 42.

The slide'member 46 is adapted to be shifted between an axiallycollapsed or fully telescoped position within the channel member 34shown in FIGS. 4 and 6 and an extended position such as that shown inFIG. 2. In order releasably to retain the slide member is a desiredadjusted position relative to the channel member 34, latch means isprovided between the members. More specifically, an elongated recess 54having an inclined bottom is formed in the upper or inner side of theslide member 46 adjacent the inner end 50 thereof as shown best in FIGS.5 and 6. A latch element 48 is secured toe a fiexure spring 52 which ismounted in the recess 54 and fixed by a fastener 56. The structure ofthe fiexure provided for pivotally I spring 52 is such that the latchelement 48 is spaced slightly from the end 50 of the slide member 46 andis normally resiliently urged to the position shown in FIG. 6 in whichthe outwardly facing surface of the latch element 48 is flush with thebottom or outwardly facing surfaces of the flanges 40 and 42 and theslide member 46, or at least does not project beyond the outer sur faceof the flanges. The bottom of the slot or recess 54 provides a stopengageable with the fiexure spring 52 for limiting outward movement ofthe latch element 48.

The member 34 has sets of notches 58, 60 and 62 formed in the flanges 40and 42 at spaced intervals as shown in FIG. 5. The notches 58, 60 and 62are adapted selectively to receive projecting ends of the latch element48 for releasably locking the slide member 46 with respect to thechannel member 34.

In order to adjust the slide member 46 relative to the channel member34, an operator first presses the latch element 48 upwardly or inwardlysufficiently to disengage the latch element from the notches. Then theslide member 46 may be freely axially adjusted relative to the channelmember. During such axial adjustment, the ends of the latch elements 48will ride on the inwardly facing surfaces of the flanges 40 and 42. Theaction of the flexure spring 52 is such that when the latch element 48comes into registry with a set of the notches 58, 60 and 62 during suchaxial adjustment, the latch element will be automatically snapped intosuch notches unless manually restrained by the fingers of the operator.

As shown best in FIGS. 6, 7 and 8, the channel member 34 has an externalcross-sectional configuration of substantially the same size and shapeas that of the opening 26 through the fitting 24. Furthermore, the

slide member 46 has a cross-sectional configuration complementary tothat of the channel member as does the member 47 of the handle or gripelement. As a result, the pushbar device serves effectively to fill andseal the opening 26 through the fitting so as to prevent the passage ofinsects or other foreign material therethrough. In this connection it isimportant to note that the latch element 48 is constructed and arrangedso as to be housed completely within the channel member so that it doesnot interfere in any way with the margins of the fitting or guide member24 during sliding movement of the pushbar through the fitting. In otherwords, there is no necessity of providing the fitting with a specialnotch or recess so as to obtain clearance for the latch element as is,done in certain heretofore suggested structures.

The members 34 and 46 of the pushbar device may be formed from variousmaterials such as wood, plastic or metal. In any event at least one ofthe members and preferably the slide member 46 is constructed from aresilent material so as to enable the member to bend as indicated inFIG. 2 for accommodating the swinging or pivotal movement of sash duringadjustment of the sash between the closed and open positions.

The pushbar device is provided with hinge means 64 for connecting theslide member 46 to the sash member 14. The hinge means comprises a firstmember 66 having transverse cross-sectional dimensions the same as thatof the opening '26 through the fitting so that the member 66 may alsoserve to seal the opening when the window is in the closed position. Themember 66 has a reduced thickness portion 67 overlapping an end of theslide member 46 and pivotally connected thereto by a pivot element 68 soas to enable the slide member and channel member to be shifted betweenthe broken and full line position shown in FIG. 3.

The hinge means has a pivot element or member 70 presenting oppositelyextending pintles 72 and 74. The member 70 has a shank 76 extending intothe hinge member 66 and secured thereto by a suitable fastener 78. Thepintles 72 and 74 project into axially aligned apertures and 82 formedin spaced apart generally parallel ear portions 84 and 86 of a secondhinge member or element 88. The ear portions of the hinge member 88 areconnected by a transverse bight portion 90 having an aperture 94therethrough for accommodating a screw or fastener 94 used for securingthe hinge member 88 to the window sash 14.

It will be noted that only a single screw is used for securing the hingemember 88 to the sash, which screw is positioned so as to besubstantially bisected by a vertical plane containing the longitudinalaxis of the pushbar device. In order to facilitate assembly of the screw94, or in other words, in order to provide sufiicient clearances for thescrew without increasing the size of the hinge member 88 so that itcannot fit easily within a suitable recess 95 formed in the window framemember 20, the screw accommodating aperture 94 is offset above thepintle accommodating apertures 80 and 82. Preferably the pintleaccommodating apertures are disposed below a horizontal plane bisectingthe ears 84 and 86 while the axis of the aperture 92 is disposed abovesuch horizontal plane. Furthermore, the pivot member or element 70 isformed with a recess 97 in an edge thereof facing the screw 94, whichrecess extends substantially through the common axis of the pintels 72and 74. This provides additional clearance for enabling a screwdriver tobe applied to the screw 94 when the hinge member 66 is swung downwardlyfrom the horizontal position during assembly of the hinge device withthe window sash.

While a preferred embodiment of the present invention has been shown anddescribed herein, it is obvious that many structural details may bechanged without departing from the spirit and scope of the appendedclaims.
